And all manager Terry Collins knows is this — he’ll be rooting hard for Harvey to make it back in due time and in full health. But it will also be very hard not to think about what and who is absent from his starting rotation.

Meanwhile, the Mets have set their starting pitchers for the first six exhibition games. Of course, as they say, it’s subject to change.

Rafael Montero will get the nod for the spring opener against the Washington Nationals this coming Friday, February 28 at Tradition Field. On Saturday — also at home — John Lannan will face the Miami Marlins. The first road game comes on Sunday in Jupiter, and Daisuke Matsuzaka will go against the St. Louis Cardinals.

Young phenom Noah Syndergaard will get the ball when the Mets take on the Atlanta Braves Monday at Disney World. The Mets are back home Tuesday, March 4 and Jon Niese will throw against the Houston Astros. Then there’s a split-squad day on Wednesday March 5 — Bartolo Colon will face the Marlins in Port St. Lucie, while an undetermined starter will go against the Nationals in Viera.
